Pump Modeling

Pump



Start Hysys



Go to the file menu select New followed by case or press CTRLN



Define the simulation basis by adding components and specified Fluid package

Defining Streams 

To define material stream press F11 or select it from the object palette (press F4 for object palette tab)



Light blue is the undefined material stream



Define Pump inlet stream with conditions and composition (100% water) as shown in following figure.



Add second stream named as outlet and pressure 84 bars.



The completely dark stream appears as ‘Dark Blue’.

Adding unit operation 

Press F12 or F4 to select from object palette



Add pump



Double click on the pump P-100 to open the pump window and complete the connection page as in the following figure



Once a pump has enough information a green bar appears at the bottom of the window indicating that everything is ‘OK’.

Specifying pump efficiency 

Default efficiency for pump is 75%, to change it do the following steps.



Click on the design tab of pump window then click on parameters.



In the adiabatic efficiency tab enter 10. This unit should be in percent as shown in following figure.



After the efficiency is entered the streams of the pumps should be solved
